ABSTRACT

INTRODUCCIÓN: la enfermedad hemorroidal se presenta en 50% de adultos mayores a 40 años, siendo la principal indicación de cirugía anorrectal y el dolor su principal complicación. Múltiples fármacos, tópicos y sistémicos, se han investigado para control del dolor, no obstante no existe un tratamiento ideal. El metronidazol ha demostrado disminuirlo, pero su uso no se ha generalizado. OBJETIVOS: evaluar el efecto de administración oral de metronidazol versus placebo en el control del dolor posthemorroidectomía. MATERIAL Y MÉTODOS: ensayo clínico controlado en pacientes adultos con hemorroides grado III/IV. Los del grupo de estudio (GE) recibieron metronidazol 500 mg oral cada 8 horas por 7 días y los del grupo control (GC) placebo. Se evaluó dolor postquirúrgico con escala visual análoga (EVA), consumo de analgésicos y reincorporación al trabajo. RESULTADOS: se incluyeron 44 pacientes, 22 en cada grupo, sin diferencias en la distribución demográfica. La evaluación del dolor postquirúrgico fue de 3,86 ± 0,56 y 6,64 ± 1,49 para GE y GC a las 6 h, de 5,59 ± 1,33 y 8,82 ± 0,79 a las 12 h, 6,86 ± 1,49 y 9,73 ± 0,45 a las 24 h, 5,32 ± 2,10 y 9,50 ± 0,59 al cuarto, 3,14 ± 1,03 y 7,36 ± 1,39 al séptimo, 2,14 ± 0,46 y 5,45 ± 1,29 al 14 día, significativo a favor del GE. La primera dosis analgésica se requirió a las 7,09 ± 2,36 h en el GE y 21,27 ± 5,47 horas en el GC (p < 0,05); tiempo del consumo de analgésicos 6,86 ± 1,61 y 13,09 ± 2,48 días (p < 0,05) y reincorporación al trabajo a los 7,59 ± 1,56 y 14,73 ± 3,76 días (p < 0,05). CONCLUSIONES: la administración oral de metronidazol es eficaz para el control del dolor post-hemorroidectomía


INTRODUCTION: Hemorrhoidal disease occurs in 50% of people aged > 40 years and is the most common reason for anorectal surgery. Pain is the main complication. Multiple topical and systemic drugs have been investigated for pain control, but there is no ideal treatment. Metronidazole has been shown to decrease postoperative pain but is not used widely. OBJECTIVE: To evaluate the effect of oral metronidazole versus placebo and to assess postoperative pain following hemorrhoidectomy. MATERIAL AND METHODS: Controlled clinical trial in adult patients who underwent elective hemorrhoidectomy for grade III/IV hemorrhoids. Patients were assigned to receive metronidazole (500 mg q8 h orally; study group, SG) or placebo (control group, CG) for 7 days after surgery. Pain was assessed using a visual analog scale after surgery. Analgesic administration (time and use of analgesics) and resumption of daily life activities were also assessed. RESULTS: Forty-four patients were included, 22 in each group. Postoperative pain differed significantly between the SG and CG at 6 h (3.86 ± 0.56, 6.64 ± 1.49), 12 h (5.59 ± 1.33, 8.82 ± 0.79), 24 h (6.86 ± 1.49, 9.73 ± 0.45), day 4 (5.32 ± 2.10, 9.50 ± 0.59), day 7 (3.14 ± 1.03, 7.36 ± 1.39), and day 14 (2.14 ± 0.46, 5.45 ± 1.29). The first analgesia dose was required at 21.27 ± 5.47 h in the CG and 7.09 ± 2.36 h in the SG (p < 0.05), the time of analgesic use was 6.86 ± 1.61 days in the CG and 13.09 ± 2.48 days in the SG (p < 0.05), and resumption of daily activities occurred at 7.59 ± 1.56 days in the CG and 14.73 ± 3.76 days in the SG (p < 0.05). CONCLUSION: Oral administration of metronidazole is effective in pain management after hemorrhoidectomy
